Andre Villas-Boas has said he is confident Spurs can secure third place - and with it automatic Champions League qualification - at the end of the season.
Chelsea's draw against Southampton on Wednesday means they are only two points ahead of Spurs, having played the same number of games, and Villas-Boas described that gap as "nothing".
"I think, after the draw, we looked positively into it. Two points from third place is nothing in the Premier League, as you know," the Portuguese said.
"Both teams face very, very hard games this week: Chelsea-Arsenal, us against Manchester United. Everton, knocking on the door, go to Southampton, so I think it can shift very, very quickly.
"Obviously we want to continue to progress. I told you last week our idea was to bring [Manchester] City into the frame, but we couldn't get all three points at QPR.
"Man City could get them against Arsenal so, you know, we have to concentrate on what's around us, and what's realistic now, and that's to get closer to Chelsea."
Villas-Boas said he believed Sunday's match against Manchester United at White Hart Lane would be an indicator of Tottenham's potential for the rest of this season.
"It will be a good reference, this game, regarding what we want to achieve towards the future, if we want to challenge for trophies," he explained.
